Abstract

Organometallic complexes of lanthanides with a well-defined stoichiometry which can be used in the stereospecific polymerization of unsaturated monomers, can be represented by the general formula: Me(OR)3*(Me1R<1>R<2>R<3>)x wherein, Me represents a metal with atomic number 21, 39, or an atomic number between 57 and 71, OR is an alkoxylic group of an alcohol; Me represents a metal of the group IIIB, whereas R<1>, R<2>, R<3> can be H, or a linear, branched or cyclo-aliphatic alkyl radical containing from 1 to 10 carbon atoms and x is an integer (3 or 4) and depends on the type of alkoxide used. The preparation of the complexes is described and their use in the stereospecific polymerization of unsaturated monomers.
